The hand anatomy presents general patterns in motor and sensitive nerves distribution. However, is possible to find some variations that are very important for the surgical anatomy of the region. We study 20 hands of 10 cadaver individuals, fixed in 10% formaldehyde solution. We found in 19 hands (95%) that the ulnar proper palmar digital nerve of the little finger was a direct branch of the ulnar nerve and only one case (5%) - of female cadaver ­ we observed one branch originated from the forearm, which was a part in the formation of the nerve mentioned above. This branch originated from the trunk of the ulnar nerve, distal to the origin of the dorsal branch of this nerve, proximal to the pisiform bone. This nerve passed through of the abductor digiti minimi muscle and then it emerged by the superficial face of this muscle, 11,3 mm distal to its origin in the pisiform bone. Then, it joined to the ulnar proper palmar digital nerve of the little finger, distal to mentioned bone. Although the literature describes innumerous variations in the formation and distribution of the hand nerves, this disposition is rare and has not been mentioned.
